SEPM vs LiveUpdate Administrator

I'm trying to figure out whether LiveUpdate Administrator makes sense to deploy.  On the surface, I can't see any benefit.  Within SEPM, I see there are tweaks to allow for installing client patches via LiveUpdate, but this isn't working.  Would LiveUpdate administrator allow for pushing client patches to managed clients or am I still up against using other tools for getting them deployed?  With nearly 2k clients, I have about 20 different builds represented and am trying to get them all updated to the latest build.  Assigning Install Packages for each of my groups has about a 50% success rate, so I more heavily rely on client patches.

Thanks,
Joel
